Defence spending has been growing as part of a drive by President Vladimir Putin to restore Russia’s military might. The decision to cut shows, however, that even the armed forces are not immune to a slowing Russian economy, which has been hit by falling oil prices and Western sanctions.

The 5 percent cut, if approved by Putin, would be the biggest reduction in defence spending since he took office in 2000.

In 2011, while prime minister, he announced plans to revitalize the Russian army and its aging equipment by spending 23 trillion roubles by 2020. Military interventions in Ukraine and Syria have made strengthening the military an even greater priority for the Kremlin.

The cut represents a victory for the finance ministry, which has said Russia can no longer afford the multi-billion-dollar revamp of the armed forces and called for a 10 percent spending reduction across ministries.

The Russian economy shrank by 3.7 percent last year and is expected to decline by another 1 percent this year.
